Experiments on steam explosion by interaction of water with silicate melts
TLDR
An experimental set-up for the generation of mixtures of silicate melt (remolten volcanic rocks) and water and the triggering of steam explosions was built at the Institut fur Kernenergetik (IKE) at Stuttgart as discussed by the authors.About:

Magma fragmentation by rapid decompression
TL;DR: In this paper, the results of a laboratory investigation of pyroclast formation following rapid decompression were reported, showing that even relatively cool magma bodies can be very hazardous when subjected to rapid unloading events.
Journal ArticleDOI
The fragmentation threshold of pyroclastic rocks
TL;DR: In this article, the authors defined the fragmentation threshold as the minimum pressure differential that leads to complete fragmentation of the pressurized porous rock sample, which is defined as a critical pressure difference between the bubbles and the surrounding magma.
Journal ArticleDOI
Fragmentation of basaltic melt in the course of explosive volcanism
TL;DR: In this article, the authors used pyroclasts from remelted volcanic rock (olivine-melilitite) to enhance interpretation of fragmentation mechanisms during explosive volcanism.

Root zone processes in the phreatomagmatic pipe emplacement model and consequences for the evolution of maar–diatreme volcanoes
TL;DR: The root zone of maar-diatreme volcanoes has been studied in this article, where the root zone is the site of the phreatomagmatic explosions and thus functions as the engine for pipe formation.
Maar-Diatreme Volcanoes, their Formation, and their Setting in Hard-rock or Soft-rock Environments
TL;DR: In this article, the formation and growth of maar-diatreme volcano type, the second most common volcano type on continents and islands, is reviewed applying the phre- atomagmatic model of its formation.

Mechanisms of hydrovolcanic pyroclast formation: Grain-size, scanning electron microscopy, and experimental studies
TL;DR: In this paper, the authors analyzed over 200 samples of hydrovolcanic ash and determined five pyroclast shape types: blocky and equant, vesicular and irregular with smooth surfaces, moss-like and convoluted, spherical or drop-like, and plate-like.

Quantitative experiments on phreatomagmatic explosions
TL;DR: The TEE-Haus (Thermal Explosion Experiment) as mentioned in this paper is an experimental set-up for controlled generation of thermal explosions (Fuel Coolant Interactions) has been built by an interdisciplinary research group of volcanologists, physicists and engineering scientists.

Detonation of fuel coolant explosions
S.J. Board,R. W. Hall,R. S. Hall +2 more
TL;DR: In this paper, a simple one-dimensional model of a system in which the two liquids are initially coarsely mixed, and show that there is the possibility of an extremely violent thermal explosion, the structure of which is analogous to that of a detonating chemical explosion.

Phreatomagmatism and its relevance
TL;DR: In the field of petrology, the relevance of phreatomagmatism is realized increasingly because it takes place in many diverse environments and affects not only small monogenetic volcanoes but also large volcanoes.
